`Application l'ed November 19, 1924. Serial No. 750,919.

The invention relates toclevis hooks, and has for its object to provide a device of this character formed from oppositely disposed lll-shaped members having one pair of their arms pivoted together, and terminatingin outwardly extending registering hooks adapted to extend through spaced apertures in a draftbar. y

A. further objectis to provide a pivoted 1.o finger between the pivoted arm, which' pivoted `finger engages the ends of the hooks and forms means for preventing the hooks from coming out of the apertures of the draft bar. c y A further object is to position the free arms of the U-shaped members whereby when the hooks are in the draft bar andin registration, said arms will' engage each other after passing throughan aperture 2a ci' a farm implementwhich is to be moved forwardly.

W'ith the above and other objects in view` the invention resides in the combination and arrangement ofV parts as hereinafter i set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the 'scope of what is claimed without departing from the spirit of the'invention.

oted latching finger. Y n t Referring to the drawing, the numerals l and 2 designate oppositely disposed U- shaped members, the arms 3 of which overlie au each other and are pivotally connected together at 4. Arms 3 terminate in outwardly extending hooked arms 5, which register with each other and are adapted to be disposed in spaced apertures 6 of a draft bar at 7, which may be carried by a tractorV or any other suitablevehicle. When the arms 5 are in registration as shown in Figure l,

the arms 8 of the U-shaped members 1 and 2 engage each other and are in alinement,

5o therefore it will be Seen that when draft is applied to the device with the arms 8 extending through an aperture 9 ofthe bar 9, which may be attached to a plow or other farm implement, the U-shaped members will et remain in relative position. However as Figure 3 is a perspective view of the'pivtractors and vehicles or articles pulled thereby move over rough and uneven ground, y there is danger of the hooks 5 Vworking out of the apertures 6, and to obviate this difii- .culty a pivoted finger l0 is provided, which e0 is pivotally connected at 4 between the adjacent overlapped endsv of the arms 3, and

which pivoted iinger extends outwardly,

and engages the inner sides of the hooked members 5 iat `l1, and prevents the hooks c5 from coming out of the apertures 6 under n normal working conditions.

When it is desired to remove the hooks from the apertures 6the operator places his finger in the recess 12 and forces the 70 pivotedl iinger lO-upwardly, thereby allowing the clevis to ybe tilted and hooks 5 removed from the apertures 6. It will also be seenthat the recessl l2 may be elimii nated if desired, and after the hooks have l been removed from` the apertures 6, the Uf shaped members l and 2 may be spread apart for removing the arms 8 `from the aperture 9 of the bar 9a. l f l From the .above it will be seen that a 8o clevis hook is provided, which is simple in construction, provided with double hooks for hooking into spaced aperturesoi:l a draft bar, and` that la single pivoted finger is provided for cooperating with both hooks'and v535 maintaining said hooks in the spaced aper` tures of the draft bar.l

The invention having been set forth what shaped members in the same plane, arms of Y `said U-shaped members extending towards each other and en aging in axial alinement, the other arms o said U-shaped members being overlapped, a pivot bolt extending u `through said overlapped arms, registering hooked members carried by said overlapped arms, said hooked members being spaced from each other and spaced outwardly from they plane of the opposed U-shaped mem-y 10o e GEORGE ZnnNLE.`
